FLOOD-GATE.

, Specification of Letters Patent.

Patented Oct. 22, 1907.

Application tiled March 5. 1907- Serial No. 360.680.

To all whom it may concern:

Be it known that I, STEPHEN S. BROWN, a citizen of the United States of America, residing at Medicine Lodge, in the county of Barber and State of Kansas, have invented new and useful Improvements in Flood- Gates, of which the following is a specification.

This invention relates to flood gates, and one ofthe principal objects of the same is to provide a strong, durable structure in which the gate is mounted on rollers to roll upon the platform and supported upon rollers mounted to travel on wires or cables against the current of the stream.

Another object of the invention is to provide means for securely bracingrthe upright members of the gate frame.

These and other objects may be attained by means of the construction illustrated in the accompanyingr drawings, in which:

Figure 1 is a plan view of a flood gate made in accordance with my invention. Fig. 2 is a front elevation of the same. Fig. 3 is a detail side elevation of the adjusting lever for tightening the bra-ce cable.

Referring to the drawings for a more particular description of my invention, the numeral 1 designates a platform to which are secured the upright gate posts 2, 3, fence posts 4, 5, upright bracing posts G, and anchor posts 7 and 8. The side guard boards 9 are secured at their front ends to the gate posts 2, and 3, and at their rear ends to the bracing posts 6, said guard boards diverging at their rear ends, as shown in Fig. l of the drawings. A bracing cable 10 passes through the gate post 2 and is secured in place, as at 11, in any suitable manner, said cable extending through the guard boards 9 and through the gate post 3, and is provided with a loop 'l2 engaged by an adjusting rod 13 extending through the post 5, and provided with a threaded end 14 fitted with an adjusting nut 15 for tightening the cable 10. A cable 1G is secured to the post 7 and extends up over diagonally disposed grooved rollers 17 journaled in the upper ends of the posts 6, said cable extending from the post 7 over the grooved rollers 17 and terminating in a loop 1S connected to an adjusting rod 19 passing through the post S, said adjusting rod being threaded as at 20, said threaded portion being fitted with a milled nut 21 provided with an adjusting lever 22 for tightening the cable 16 and serving to brace the structure and aid in giving rigidity to the frame of the gate. Stretched from the cable 16 to the cable l0 are parallel trolley wires or cables 23. The flood gate 24 is provided with upwardly extending vertical bars 25 and journaled near the upper ends between said bars are grooved rollers 26 designed to run upon the trolley wires 23. .lournaled between the upright bars 25 near the lower edge of the gate 24 are rollers 27 which bear l upon the platform l when the gate is in its lowermost position, and a bowed spring 2S is secured to the platform l back of the gate 24 to form a stop for the gate until said gate is overcome by the strength of the current. At the opposite sides et the gate are guard fences 29 made up of boards 30 and slats 31, said fences being set at an angle to the gate, as shown more particularly in Fig. 1. Suitable cross braces 32 extend between the posts G and 7, and G and 8.

The operation of my invention may be brieiiy referred to as follows: The platform 1 being placed in the bed of a stream the current coming against the gate 24 will raisethe same sufficiently to let the water pass and `automatically drop to the position shown in Fig. 2 when the current is not of sufiicient strength to raise the gate and to overcome the weight of the gate over the bowed spring 28. Whenever it is required to tighten the frame, the lever 22 and the nut 15 are turned upon the adjusting rods 19 and 13.

From the foregoing it will be obvious that a flood gate made in accordance with my invention is strong and durable, the frame maybe readily tightened, that the flood gate will rise and fall to compensate for the strength of the current, that the device as a whole may be manufactured at slight cost, and is very efficient in use.

Having thus described the invention, what I claim is:

l. In a iiood gate, a frame composed of upright posts, cables stretched across said posts, wires connecting said cables, a Hood gate provided with rollers which travel on said wires, and rollers at the bottom of said gate.

2. A Hood gate comprising a platform, guard fences at opposite sides of said platform, upright posts to which said guard fences are secured. a cable passing through two of said posts and connected to an adjusting rod provided with means for adjustment, upright bracingl posts provided with rollers, anchor posts, a cable extending from said anchor posts over said rollers, and means for adjustingl said'cable, and a flood gate provided with rollers and wires connected to said cables upon which said rollers arel supported.

3. In a flood gate, the combination of transversely extending cables connected by longitudinal wires, a gate provided with rollers adapted to run on said wires, a platform, rollers on the gate adapted to bear upon the platform, and a bowed springl ou the platform in rear of the gate.

In testimony whereof, I aiiix my signature in presence of two witnesses STEPHEN S. BROWN.
